ANOMALY OF ACCURACY LEVEL IN NOISE METER APPLICATION

Currently the use of smartphones is not only used as a means of exchanging information, but the sophistication of this mobile phone also offers many applications that can be used in daily activities. One of the applications available on a smartphone is a noise meter. The many types of noise measuring applications available on smartphones make it easier for users to select and use these applications. Therefore, it is necessary to know the accuracy of the noise meter application available on smartphones. So that it can be an alternative for users in choosing a noise level measuring application. This study measured the noise level in Taman Kota Wisata Cibubu and the Physics Laboratory of the Christian University of Indonesia. This study compared 5 android-based noise meter applications with a sound level meter. Through this research it is known that the SPL Meter application version 1.0.3 has a high sensitivity level in noisy locations with an accuracy level of 93.96 percent, while the Sound meter application version 1.7.2 has a high sensitivity level at locations that have relatively small noise levels, with an accuracy rate of 82.41 percent.
